About TET2

No gene-level summary was recorded for this case.

LYFE Sciences is an AI system, and it can make mistakes. Criteria may be applied incorrectly, sources may be misread, and a confident-looking classification can still be wrong. Double-check every criterion and its underlying evidence before relying on any call.
01The reasoning

How it was classified

The recorded framework is Not recorded. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.

This variant is present at extremely low frequency in population databases: gnomAD v2.1 AF=0.00142% (4/282,248 alleles), gnomAD v4.1 AF=0.00056% (9/1,614,034 alleles), grpmax FAF=7.04e-06. Absent from gnomAD-Canada. Frequency is well below the 0.1% PM2 threshold for a rare disease variant.

Benign criteria applied · 1
BP7Supporting
BP7 · supporting

This is a synonymous variant (p.Ser471=) for which SpliceAI predicts no impact on splicing (max delta score = 0.00; no donor gain, donor loss, acceptor gain, or acceptor loss). No evidence of cryptic splice site creation. The variant meets BP7 criteria for a silent variant without predicted splice impact.

Recorded classification: Uncertain significance

gene-specific framework lacked a usable explicit final combination framework, so generic ACMG/AMP 2015 final-combination rules were applied as fallback; applied criteria: PM2 supporting, BP7 supporting benign; combination = 1 supporting + 1 supporting benign, which maps to VUS.

NM_001127208.2:c.1413C>T (p.Ser471=) is a synonymous variant in TET2 at extremely low population frequency (gnomAD v2.1 AF=0.00142%, 4/282,248 alleles; v4.1 AF=0.00056%, 9/1,614,034 alleles), meeting PM2 at supporting level.

SpliceAI predicts no splicing impact (max delta=0.00), meeting BP7 (supporting benign) for a synonymous variant without predicted splice alteration.

ClinVar contains a single submission classifying this variant as Likely benign (Ambry Genetics, criteria provided), though no expert panel review exists. PS5 and PP5 are not met as the classification is not pathogenic.

No variant-specific literature, functional studies, de novo observations, or segregation data were identified. Multiple criteria could not be assessed due to absence of evidence.

The pathogenic evidence (PM2 supporting) and benign evidence (BP7 supporting_benign) are balanced and of equivalent weight. The variant is classified as a Variant of Uncertain Significance (VUS) per ACMG/AMP 2015 combination rules.
